**Design Breakdown:**

1. **Main Subject**: Replace the beer glass with a tall, frosty glass of lemonade. The lemonade should be a bright yellow color with a few ice cubes visible.

2. **Glass Shape**: Utilize a slightly curved, frosted glass that resembles a chalice instead of a straight-sided beer glass.

3. **Background**: Maintain a blurred, natural outdoor background but transition it to a sunny park setting with hints of green foliage and soft sunlight filtering through the leaves.

4. **Additional Elements**: Add a slice of lemon on the rim of the glass for a decorative touch, and consider including a colorful straw inside the lemonade.

5. **Lighting**: Implement warm, naturally diffused sunlight to enhance the refreshing appearance of the drink, creating a bright and inviting atmosphere.

6. **Surface**: Change the surface beneath the glass to a rustic wooden table to create a casual, outdoor vibe.

These changes will create a fresh, summery image that emphasizes a different beverage while maintaining a similar composition and feel.
